TOOLS for you to further research on your own include: action plan, two steps down, 30/60/90 day cycles, brainstorming, Six Thinking Hats®, using an affinity diagram, driver diagrams.
Having produced an action plan, the next stage is to put some target dates against these actions and decide who undertakes them. This provides a scheduled plan. It may be helpful to convert this into a format that all participants can easily see. This should clearly state key milestones for the project.
